When to Use Austin Air Allergy Machine Air Purifier?

Austin Air Allergy Machine HM405 Air Filtration System

  • The Austin Air Allergy Machine large True HEPA Filter traps from the air over 99.97% of all microscopic airborne contaminants down to 0.3 micron in size. True HEPA provides a superior protection from sub-micron airborne particles and allergens including, but not limited to: mold spores, plant spores, pollen, house dust mites and debris, lung damaging dust, pet dander, bird feather dust, microscopic ash particles in cigarette smoke and smoke from wood burning stove, etc.
  • Austin Air Allergy Machine's chemical an odor filter contains the Lightweight Cloth-embed dust carbon - HEGA.
    The HEGA is an acronym for "High Efficiency Gas Adsorption." It has a high rate of adsorption for wide variety of regular chemicals and odors. However, due to smaller amount of adsorbent used, the overall adsorption capacity is lower than for 15 lb. carbon canister in Austin Air HealthMate HM400 model. Therefore, the carbon filter can get saturated sooner and may require more frequent filter replacements.
    At the same time HEGA filter makes the Austin Air Allergy Machine HM405 about 14 lbs. lighter and makes easier to carry it up and down stairs when needed.
    Important Notice!
    Austin Air Allergy Machine's True HEPA filter and Cloth-embed dust carbon (HEGA) are combined together in One Filter Assembly. Therefore, the whole filter assembly needs to be replaced when either True HEPA or Activated carbon filter gets full.
  • Standard Polyester based Pre-filter (the first stage of the air filtration system) traps most of larger visible dust and dirt particles to protect fine True HEPA filter from faster contamination and extend its lifetime.
